ll Claim. ((Cl. 2i2t8) This invention relates to reels or coil centersof face of the body 6, in which a jaw t is fitted. the type now commonlyused to carry coils of This jaw has a number of cam surfaces 6 on metalstrip which is to be cold rolled by means of one of its sides which areengaged by cam sura l-high mill, one of the objects being to providefaces l on the side of a laterally shiftable jaw l 5 a reel of thischaracter which may be easily hanwhich is also fitted into the groove.When this dled and mounted. Another object is to provide bar islongitudinally moved the jaw will be moved an improved means forsecuring the ends of metal clrcumferentially of the body so as toeifectively strip to such reels. Other objects may be inclamp the end ofa strip between itself and the ierred. side of the groove.

The axle 2 projects 6, the bar '5 beingmoved to the right so as to beyond the ends of the body i so as toprovide permit this. Thereafter the bar is forced to the journals 2 andfluted ends 2 and end portions l left, this causing the jaw to tightlyclamp the are connected to the axle 2 and body I in any end of the stripagainst the side of the groove.
